v Be,it.kno'wn that .1, WILLIAM E. Woo'n ARD, of'schenectady, in thecounty of Schen-' ectady and State of New York, have invented a certain new and useful Improvement in Car-Trucks, of which improvement the fol-.

lowing is a specification.

' My invention relates to carj tricks of the Master Car Builders type, andits object is to provide a truck of such type which shall be of simplified construction and avoid the use of the bent equalizer forgings heretofore usually found necessary."

. The improvement claimed is hereinafter fully set forth.

' In he accompanying drawings: Figure 1 is a plan'or top view, partly in section, of a car truck embodying my invention; Fig. 2, a

side view, in elevation, of the same, and; Fig. '20. 3,,atransverse central section;

- In the practiceof my invention, 1 provide a truck frame com- ,osed of two straight side members, 1, of c annel section, andtwo transoms, 2, of-angle section, connecting the slde members one to the other, on opposite sides of the trans-Verse central plane of the truck. The transom's are secured to, the

side members through t'h' e' intermediation of filling castings, 3, the websof which are bolted to the side members, and which have lateral flanges bolted to the transoins. .The

transoms and side members are also con-' nected by gussets, 4, secured to them by vertical bolts. The I lower flanges of the side members, 1, are cut awayat and adjoiningtheir ends, and pedestals, 5, are connected to the side members at the portions thereof where said flan es are cut away, by bolts, '6, passing througi fianges, 5?, on the sides of the pedestals, toward the middle of the truck. As shown in ;s. 2 and 3, the flanges 5, are of angle-section,their vertical portions abutting against and being secure -'to the side frame memsers, and their horizontal portions serving as upper bearings for the equalizer springs hereinafter described.

The truck 1. supported on Wheels, 7, fixed on axles, 8, which are journaled in axle boxes, 9, fitting in the pedestals, 5, which, with the truck frame to which they are connected,

are movable vertically, relatively to the axle boxes, on which they are supported by equalizers, 10. The equalizers, 10, are straight bars of rectangular section, which extend longitudinally between the flanges of the side frame members and rest, attheir. ends,- on the tops vofthe axle boxes, and-, in turn support-the side members through the in; -termediatioj1 of helical equalizer springs, 111' The equalizer springs- "are coiled-around as spring rods, 12', connectediatfitheifupper ends to, a (1 de ending'froin, the equalizers, and abug at t e'ir upper-ends, against the 'horizont lportions of the flanges, 5, of the i pedestals, and, at theirlowerends, against as springlseatsfl'2 fitted on the spring rods.

' A spring plank, 13, is suspended from-the. trans ems, 2 by swing hangers, 14, journaled on swin hanger pivots, 15, which are fitted in,"sWing hanger pivot bearings, 16, on the tops'of the transoms. A swing bolster, 17, cbmposed of two parallel bars of angle sec- 't1OII WlllCl1 are 'con-nectedby end'castings, 18, is supported on the spring plank by:semi elliptic bolster springs, 19, two pairs of 75, which are inter oscd between the spring plank and each of the end'custings, 18, of the bolster. The webs of the filling castings, 3, of the transoms, serve as and stops for the bolster and wear plates for-the adgacent end castings thereof; A center casting, 20, and. side bearings, 21, of the "ordinary form, are secured "to the bolster, its .zuiddle and ends, respectively. i v

The form and relation'of the side members and edestals above described are such as to simp ify the construction and minimize the number of parts of the truck frame, and attain the further substantial advantage of en abling straight equalizers to be applied, in.- stead of those. havingnpwardly bent ends, as heretofore employed in trucks of the C. B.-type. The forgings for equalizers of the latter form are more compl cated and difficult to make, and. are subject'to the riskof injury in bending, from'which' the straight equalizers are exempt. Y Y

I claim as my invention and. desire to secure by Letters Patent:

1. In a'car truck, the combination of two side frame members of channel. section, having their lower flangescutaway at and near their ends, transoms connecting said side frame members, pedestals having lateral flanges of angle section, the vertical portions of which abut againstand are secured to the side frame members on the portions thereof at which their lower flanges are cut away, axle boxes fitting in said ede'stals, straight bar equalizers extending ongitudinally between the flanges 0f the side frame members tibn of which 'servesfor connection to a side and beanng on the axle boxes, and equahzer frame member and the honzontel portlon sprlngs beanng at then ends -on the equal as a seat or beann for an e uahzer sprmg. 10
